Be it known that I, JOHN Manczr, a sub? ject of the King of- Hungary,residing at La ',Belle, in the county of Fayette and State ofPemisylva'n-ia, have invented Acertain new and useful-Improvements inAntiskid Attachments for Tires, of which the following is. aspecification.

This invention relates to certain nev,7 and vuseful improvements inanti-skid attach- Vments for tires.

An object of the invention is to provide `nenti-skid attachment forautomobile tires that may be easily and quickly mounted on the Wheel anddetached therefrom, shouldv the saine become broken or otherwiseinjured.

A further object of the invention .is to providemeans to preventautomobile Wheels A; .from skidding, consisting of independent `.fentionis better understood, the same consists -in the novel construction,combination and arrangementl of parts to be hereinafter more fullydescribed and thenclaimed, refp erence being had to the accompanyingdraW- ing by like characters denoting corresponding parts throughout theseveral views, and in which:-

Figure 1 is a side elevational view of av portion of a Wheel lshowingthe anti-skid attachments secured thereto. Fig. 2 is a cross sectionalview taken on the line 2-2 of Fig. 1, illustrating the manner ofsecuring the anti-skid shoes to the tire, and F ig. 3 isa -vieiv'takenon line 3 3 of Fig. 2. "Referri'ng .more specifically-to the drawingaccompanying this application and in .which is shown a preferredembodiment of my invention, the reference numeral designates a pneumatictire or the usual construction mounted upon the rim 11. Means areprovided to, prevent the tire 10l from skidding or slipping over Wetstreets or uneven roads and consists of a shoe 12 that is preferablytriangular in crosssection as clearly shown in Fig. 3. The shoe 12 4hasa knifev edge 13 which constitutes the road 'engaging portion and issuitably curved as shown Ain Fig, 2 to engage the tread sur- Speecationof Letters Patent.

yface ofthe tire 10 for the major portion of its length. Any suitablematerial may be utilized for the construction of the shoes 12 but it ispreferably desired Vthat the'same be made of metal. Each end of the shoe12 1s projected outward from the tire and provided With a transverseopening 11 for the reception of a ring 15 that constitutes a' part ofthe means for securing the same to 4 with parallel. ears laiprovidedwith regis-.

tering openings to receive the threaded bolt 19,-an adjusting nut 20.being mounted on lthe threaded end of the bolt 19 and 'engaging theadjacent inner end 18 of the arm 16 whereby the shoe 12 is secured tothe Wheel.

From the above description ofthe device it Will be readily apparent thatshouldY any one of the anti-skid shoes l2 become broken' or otherwiseinjured, the same may be readily removed from the tire 10 by removingthe nut 20` from the bolt 19 which Will permit the-arms 16 to beseparated at their upper ends and thereafter displacetheii hooks 17 fromthe rings 15 carried by the 4shoes 12. A new shoe may then replace'theold one and be mounted upon the tire 10 in a manner as above described.

The form of the shoe-especially adapts it for co-action with theclamping arms employed. It Will be'I noted that the triangularcross-sectional contour of the shoe presents a` Wide inner surface toContact with the tread surface of the tire, and the ends of the shoeproject outward from the radialv plaies of the sides of the tire to`insure a direct` radial tension upon the ends of theshoe to firmly clampits, broad inner face adjacent the tire. This feature of contact. withsimilar shoes locz'itedjr adjacent thereto.

I claim An anti-slidding'- attachment'v -for-f-wheel tires comprising ashoe of segment form perforated ends for clamping the segment 10triangular in cross-section throughout its to the wheel felly. Wcurvilinear length and having its inner face 'll-n testimon whereof laffixmy signature conforming to the tread of the tire, the in presenceo',tvvo' witnesses.
